rMPRovED FLouR-SIFTl-:R

Specification forming part of Letters Patent No. 48,156, dated June 13,1865.

To all 'whom t may concern:

Be it known that I, DANiEL (l. COLBY, of`

Claremont, in the county of Sullivan and State ot' New Hampshire, have invented certain new and useful Improvements in Flour and Meal Sifters for Family Use; and I do hereby declare the following is a full and exact description of the same, reference being had to the drawings that accompany and form a part of these speciications, in which- Figure 1 isa perspective view, with a portion ofthe front and a portion ot' the cover removed,

.so as to show the arrangement of the interior parts; Fig. 2, a perspectiveview, showing some of the partsin adift'erentposition; Fig. 3, view of the lour-b'ox removed from the other part, to which it is usually attached; Fig. 4, a view ofthe part containing the sieve detached from the flour-box, on which `it ordinarily rests, as in Fig. l; Fig. 5, a sectional view, showing those parts that are brought to bear directly upon the lour or meal to be sifted.

Letter A represents a cylinder containing a perforated bottom forming a sieve; letter B, a

` box or receptacle to receive the our as it falls from the sieve; O, an upright shaft standing in the center of the sieve; D, a bar arranged on the shaft C, somewhat above the perforated bottom ot' A, yet extending quite across its diameter E E, narrow strips of leather or wood attached to the under side of the crossbar D, and resting on the upper surface of the sieve; F, a cross-bar just below the bar D, passing through the center ot' the lower end of the shaft O, and has its ltwo ends curved in opposite directions, (as seen in Fig. 4 or 5;) G G, braces to sustain thel shaft C in its proper position; H, alever to revolve the shaft C by; I, a cover tting both A and B, as may be seen in Figs.

-1 and 3. j is a hinge joining the cylinder A with the lower cylinder or flour-box, B; k, a loop attached to the box B directly beneath 111e hingej; l, a hook on the cover I, made to insert in the loop lr, as seen in Fig. 2. This hook has also an eye to it it for the hingej when the cover is used upon the box B, as in Fig. 3. m is a pin, made of wire, to connect the joint of the hingej, and, being provided with a loop at one end, is easily withdraw; u, a screw passing up through the perforated bottom or sieve, through the bar F, and some distance intothe shaft U, and serves to keep the lower end of this shaft in place; o o, handles, one on the two opposite sides of the iiour-box B, to carry it by. N f

`The object ot my invention is .to provide a neat and compact family sieve, one that obviates the necessity of applying the hands to the flour or meal, and one thatY secures great rapidity in sifting, and at the same time throws oft' no tine Hour-dust about the pantry or over the clothes of the operator; and, furthermore, torprovide a ready way of pouring oi` the bran without disturbing that part of the apparatus which contains the meal already sifted; and, alsoto provide a convenient method of detaching that part of the apparatus containing the sieve whenl it may be desired Afor separate use, and to have the parts so arranged that the our or meal, after it has been sifted, may be poured ont for use as handily as from a simple bucket or pail, without the use of slide or shovel.

rlo show clearly how I secure these desirable qualities, and to enable others skilled in the art to make and use my invention, I will de scribe more fully its construction and inode of operation,

I make the cylinders A and B of wood or platetin, the perforated bottom of A usually of wire-cloth, fastened on in the ordinary manner of making sieves.

The drawings will sufficiently illustrate the manner of combining the cross-piece D, the curved bnr F, and the lever H to the shaft C.

The braces G G are made of stout tin, folded and bent around the shaft Gjust above the bar D, with a rivet to keep the loop around the shaft from opening. These braces, the two parts ot' the hingej, the loop la, the hook l, and the handles o o are riveted to the parts to which they are attached. Y

The strips E E are arranged angling to the bar D, so that when there is a large quantity of flour in the sieve a portion of it may slip through between these strips and be thrown, nearer the center of the sieve, thus relieving the otherwise too great strain upon the shat't (l and attaching parts, and also preventing the flour from being thrown too much to the outside of the sieve by centrifugal force, as it would most assuredly be were these strips arranged straight along the .bar D.

The bar F is curved on each side of the shaft C, and operates also to keep the our from be` ing forced out against the rim of the sieve, and serves also to keep the flour evenly distributed the cover I. In case the box B at any time that the cover I is used to cover the top of the e sieve, as in Fig. 1, sometimes to receive the bran, as in Fig.2, atother times upon the iiourbox B, as in Fig. 3.

over the sieve. The angle of the strips E E and the curves of the bar F are such that they perform their legimate ofce when the shaft C is turned around from left to right.

The hook lis used to attach the cover I temporarily to the loop lc on the side of the ourbox B, as seen in Fig. 2. New, With this arrangement we have only to turn the sieve on its hinges, as seen in Fig. 2, and the4 bran or Whatever else there may be falls directly into contains a quantity of flour already sifted and it is desired to sift something else, the pin m is readily withdrawn and the sieve A detached, and may be used by itself like any other ordinary sieve, and the cover I meantime be used on the flour-box B, protecting the contents thereof` from dustor insects, While the sieve A isbeing used elsewhere. Thus it will be seen In sifting meal of any kind in which there is much bran to be disposed ot' my arrangement will be found of the greatest convenience, and the our may be as readily poured from the box B as from any pan or pail simply by turning the rim back on its hinges. The lour'box B not'only keeps all dust from ying about when sifting, but affords a very convenient article for keeping any not wanted for use at
